Answer guide · AC9M1M02

  1. Move equal cubes end-to-end without gaps, align the start, and measure again.
  2. No. Longer units need fewer repetitions to cover the same length.
  3. Accept a consistent count with identical units, aligned starts and no gaps or overlaps; describe any leftover part.
  4. The 9-cube strip. It contains two more of the same length unit.

If help is needed: Six large units and six small units do not show the same length. Counts can be compared directly only when the units match.
